ALUMINUM ELECTROLYTIC CAPACITOR AND METHOD OF MANUFACTURING THE SAME

摘要

THE PRESENT INVENTION AIMS TO ADDRESS A PROBLEM OF CONTACT FAILURE LIKELY TO OCCUR IN THE JOINT BETWEEN AN INTERNAL LEAD (2) AND AN EXTERNAL TERMINAL (4) AND TO PROVIDE A RELIABLE ALUMINUM ELECTROLYTIC CAPACITOR. TO THIS END, AN ALUMINUM ELECTROLYTIC CAPACITOR OF THE PRESENT INVENTION IS STRUCTURED SO THAT A THROUGH-HOLE (202) PROVIDED THROUGH AN INTERNAL LEAD (2) HAS A DIAMETER SMALLER THAN THE OUTER DIAMETER OF AN ALUMINUM RIVET (5) AND THE PERIPHERAL EDGE OF THIS THROUGH-HOLE (202) IS DRAWN TO PROVIDE A CYLINDRICAL PORTION (21) INTEGRAL WITH THE THROUGH-HOLE (202).
